RAIL-FILING- MACHINE.

Specification of Letters Patent.

Patented Dec. 30, 1913.

Application filed September 25, 1912. Serial No. 722,243.

To all whom it may concern:

Be it known that I, ALFRED CARO, a citi- Zen of the German Empire, and residing at Charlottenburg, Germany, have invented certain new and useful Improvements in Rail-Filing Machines, of which the Jfollowing is a specification.

My invention relates to a rail-filing machine for rectifying unevenness (undulations), (joints, etc.) of rails, in particular tramway rails.

The machine is adapted to be tilted, for the purpose of obtaining the pressure necessary for the liling operation, and is provided with a device which enables the machine to be held in its tilted position.

It consists in a combination of mechanism and in det-ails of construction which will be more fully explained by reference to the accompanying drawing, in which the figure illustrates my invention.

The tiltable arrangement permits oi bringing the tile-plane to bear upon and to be raised from the rails in a simple manner so that the work can be undertaken while the cars are running.

In the accompanying drawing Figure 1 is a side elevation and Fig. 2 a plan view of a rail tiling machine embodying my invention.

al and a2 designate the two wheels upon which the frame Z) rests. Upon the frame Z) the driving motor c and the driving gear are mounted. The motor acts by means of a driving rod d upon a two-armed swinging lever e on the lower end of which the thrust rod f for the file-plane g is mounted. Cn the frame a lifting arm or boom It projects toward the front, on which arm the file-plane g is suspended by means of chains or the like. At t-he rear of the wheel there are two supports 7s which can be raised or lowered. If t-he supports are lowered the rear of machine is raised and the boom tilted toward the ground in accordance with the bearing pressure required upon the tool (rile-plane). The actuation of the supports le may be eected by means of rack bars and toothed wheels and crank as shown in the drawing or in a similar manner.

I claim:

l. In a rail-filing machine, a frame adapted to rock on an axis, a motor mounted on the frame, a driving rod operated from the motor, a lever pivoted on the frame connected to the driving rod, a thrust rod connected to the lever, a filing element connected to the thrust rod, and a flexible connection between the frame and tiling element.

2. In a rail-filing machine, a frame adapted to rock on an axis, a motor mounted on the frame, a driving rod operated from the motor, a lever pivoted on the :trame connected to the driving rod, athrust rod connected to the lever, a ling element connected to the thrust rod, a flexible connection between the frame and tiling element, and means to rock the frame on its axis to raise and lower the filing element.

3. In a rail filing machine, a pair of sup-- porting wheels, a frame mounted to rock between the wheels, an oscillatory lever pivoted on the frame, a driving rod connected with the lever intermediate its ends, a thrust rod connected with the tree end of the lever, a filing element connected with the free end oi' the thrust rod, means on the frame to reciprocate the driving rod, a boom extending from the frame, a flexible member connecting the filing element and boom, and means to rock the frame to raise and lower the boom, for the purpose specified.

In testimony whereof, I ahx my signature in the presence of two witnesses.

ALFRED CARO.
